I needed a 30mm wrench for installing of a water tap. Lacking an adjustable wrench but having a 32mm wrench, I designed this small adapter.
Besides adjusting from 32mm to 30mm it also protects the chrome-plated nut against scratches from the wrench.
Of course, you can also use it with an adjustable wrench for protecting chrome-plated fixtures.
